Hi Guys
I have recently returned to the British bike fold 
I will probably get vilified for this but I have Just bought a Tribsa
which consists of an A65 frame with a Nova and a Triumph all ally
motor tiger 100 motor. nobbly tyres, ally wheels, all in boxes 
obviously trying to register the frame
and attempt to build the bike up.
I may be accepted here or directed elsewhere  I don't know
and at 65 with a dodgy left knee I'm wondering why I bought a bike with
a kickstart again
